Walker Exhaust CalCat Carb 83189: The Ultimate Catalytic Converter with Integrated Exhaust Manifold Review

I fitted this unit to my car about 2 months ago - the check engine light has gone and the problems seem to have been resolved.

Expensive but you get what you paid for. Does exactly what it is advertised for. Passed my smog test legally and am glad I did.

For anyone who needs to smoke their cars in LA, this is NOT working as instructed. Unfortunately it didn't work out in 2 different places for the same reason which is not an acceptable group number. Ps threads are cheap and soft

i had a problem smoking my car. And the muffler shop was charging nearly $3,000 for parts and labor. I found out what exhaust manifold I need, bought it on Amazon. A week later it arrived and I installed it in my car. Then first thing in the morning I went to sniff my car and everything went smoothly. I am very satisfied with this product.

Just what my old Camry needed. I had a terrible P0420 check engine light. I've tried everything from replacing the O2 sensor, PCV valve, CataClean and countless other things to get rid of the check engine light.

I replaced it 2 weeks ago, reset the check engine light and drove about 200 miles. driving cycles. The check engine light is off and the vehicle just…

This converter resolved the P0420 code and passed the California smog. The manufacturer's guarantee is 5 years/50,000 km. Mine lasts just over 4 years and 22,000 miles. P0420 comes back with the check engine light on. The car runs well, does not burn oil, does not burn coolant, the lambda probe connectors were changed when replacing the cat-converter. The MAF was also replaced along with the PCV. Revain sells the product and cannot help with the warranty and refers me to Walker. They will only…

I had a check engine light that went on and off intermittently until it finally went on solid. Eventually I decided to check the problem out and after a friend read it from a scanner it came up with code P0420 which is a manifold catalytic converter efficiency issue. After that I decided to do a little research at home and found that other things that could be causing the error could be worn oxygen sensors or spark plugs. Considering my car had 105,000 miles this was bound to happen anyway so I
